head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
The original post-apocalyptic CRPG where character builds solve the wasteland.

Optimization · Pure Optimization
A cozy occult shopkeeping game about identifying mysterious plants from books, maps, and cryptic clues.
Fallout leans Optimization (Pure Optimization); Strange Horticulture leans Optimization (Pure Optimization).
Fallout leans a little harder on execution, though the gap is small.
Fallout
Turn-based, no dexterity
Strange Horticulture
Page-turning and labelling; zero dexterity.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout
No adaptive opposition
Strange Horticulture
Customers follow a script, never adapt.
Fallout leans a little harder on variance, though the gap is small.
Fallout
To-hit rolls and random encounters
Strange Horticulture
Unknown plants and clues until identified; fully convergent.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout
SPECIAL builds and quest routing are deeply solvable
Strange Horticulture
Cross-referencing the field guide is a pure deduction system.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
